Stent for high frequency thermotherapy

The object of this invention is to provide a stent for high frequency thermotherapy, which is fabricated by knitting first superlastic shape-memory alloy wires as a way to allow the first superelastic shape-memory alloy wires to cross each other at different positions to make a hollow cylindrical stent body having a net structure with a plurality of meshes. The stent body is covered with an insulating substance. A hollow cylindrical conductive body surrounds a waist part of the stent body while any one end or both ends of the conductive body is attached to the waist part of the stent body. At this time, the conductive body is fabricated by knitting second superelastic shape-memory alloy wires as a way to allow the second superelastic shape-memory alloy wires to cross each other at different positions.
